Ranbaxy Laboratories Ltd. (RBXY) fell the most in more than three months after announcing a recall of the company’s generic version of Pfizer Inc. (PFE)’s cholesterol treatment Lipitor. Ranbaxy is pulling the pills from the U.S. because they may contain small particles of glass, the company said in a statement on its website. The recall of atorvastatin will cause a “temporary disruption” in the supply of the drug and it will take two weeks to complete an investigation into the issue, Ranbaxy said.
